Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing motorized slewing rings with large diameters is complex due to the need for numerous part adaptations, making production and maintenance difficult, especially for diameters greater than 1 meter.
Innovation Solution
The method involves using standardized magnetic and coiled blocks arranged at regular intervals on two annular rings, where one ring is fixed with coiled blocks and the other with magnetized blocks, allowing for easy modular production and maintenance by exchanging blocks individually without disassembling the entire motorization system. This design simplifies the motorization process by using linear motor blocks and flat annular surfaces for assembly, facilitating the use of the same blocks across different diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional motorization methods are used for large diameter slewing rings, then the motorization can be achieved, but the manufacturing complexity increases significantly and maintenance becomes difficult
Solution Approach 1:
The motorization system is divided into independent modular blocks (magnetic blocks and coiled blocks) that can be individually manufactured and assembled. Each block functions as a self-contained unit with standardized dimensions, allowing the overall motorization to be adapted to different slewing ring diameters by simply varying the number and arrangement of blocks without redesigning the entire system.
Solution Approach 2:
The patent establishes universal standardized blocks that can be used across different sleving ring applications and diameters. The magnetic blocks and coiled blocks are designed with standardized interfaces and dimensions, enabling them to serve multiple functions and be interchangeable across various motorized slewing ring configurations, thereby reducing manufacturing complexity while maintaining adaptability.
2Power
If numerous parts are adapted for motorization of large diameter rings, then the motorization power can be increased, but the number of parts and assembly complexity increase
Solution Approach 1:
The motorization system is divided into independent modular blocks (magnetic blocks and coiled blocks) that can be individually manufactured and assembled. Each block functions as a self-contained unit with standardized dimensions, allowing the overall motorization to be adapted to different sleving ring diameters by simply varying the number and arrangement of blocks without redesigning the entire system.
Solution Approach 2:
Multiple magnetic blocks and coiled blocks are combined in a standardized modular configuration to achieve the required motorization power. The blocks are arranged in pairs or groups around the sleving ring, with each block contributing additively to the total motor output. This merging of standardized units allows scalable power increase without proportionally increasing system complexity.
3Ease of repair
If complete motorization assembly is disassembled for maintenance, then individual blocks can be replaced, but the maintenance process becomes time-consuming
Solution Approach 1:
The motorization system is divided into independent modular blocks (magnetic blocks and coiled blocks) that can be individually manufactured and assembled. Each block functions as a self-contained unit with standardized dimensions, allowing the overall motorization to be adapted to different sleving ring diameters by simply varying the number and arrangement of blocks without redesigning the entire system.
Solution Approach 2:
Individual magnetic blocks or coiled blocks can be extracted and replaced independently from the rest of the motorization system. The standardized interfaces and modular design allow blocks to be removed and installed without disassembling the complete motorization assembly, significantly reducing maintenance time and effort while improving repair ease.

AI summary
The ring (1) has an annular fixed inner ring (2) and an annular mobile outer ring (3) rotationally mounted relative to each other along a rotational axis (X) of the ring (1), and a rotational motor e.g. synchronous motor, with a wound part (4) and a magnetic part (5). The wound part includes wound blocks (41) fixed on the fixed ring, where each wound block has an electrical conductor that forms a three-phase winding at each wound part. The magnetic part has magnetic blocks (51) fixed on the mobile ring, where the magnetic blocks having magnets (52) form a ring of magnetic blocks. An independent claim is also included for a method for manufacturing two different types of motorized slewing rings.
